Multifaceted advances in TiO <sub>2</sub> -based photocatalysts for PFAS degradation: a critical review of mechanisms, modifications, and challenges
Avtar Singh, Thiagarajan Soundappan
Abstract
TiO 2 remains central in photocatalysis, alone or in hybrids. Doping, composites, and heterojunctions boost PFAS degradation. Advanced oxidation and PEC improve defluorination. Mechanistic insights address stability, matrix effects, and scale-up.
